Scalable lithography from Natural DNA Patterns via polyacrylamide gel
A facile strategy for fabricating scalable stamps has been developed using cross-linked polyacrylamide gel (PAMG) that controllably and precisely shrinks and swells with water content. Aligned patterns of natural DNA molecules were prepared by evaporative self-assembly on a PMMA substrate, and were transferred to unsaturated polyester resin (UPR) to form a negative replica. The negative was use...
متن کاملPolyacrylamide Gel Electrophoresis
Polyacrylamide gels are typically formed by polymerization of the monomer acrylamide crosslinked to the co-monomer, N,N’-methylenebis-acrylamide, commonly called BIS. This process is a freeradical polymerization that requires an initiator, usually ammonium persulfate, and a catalyst like N,N,N’,N’-tetraethylmethylenediamine (TEMED). A distinct advantage of polyacrylamide gel systems is that by ...
متن کاملNeutral polyacrylamide gel electrophoresis.
MATERIALS 5x TBE electrophoresis buffer Polyacrylamide gels are poured and run in 0.5x or 1x TBE at low voltage (1-8 V/cm) to prevent denaturation of small fragments of DNA by Joulic heating. Other electrophoresis buffers such as 1x TAE (please see Agarose Gel Electrophoresis) can be used, but they are not as good as TBE. The gel must be run more slowly in 1x TAE, which does not provide as much...
متن کاملImmobilization of DNA in polyacrylamide gel for the manufacture of DNA and DNA-oligonucleotide microchips.
Activated DNA was immobilized in aldehyde-containing polyacrylamide gel for use in manufacturing the MAGIChip (microarrays of gel-immobilized compounds on a chip). First, abasic sites were generated in DNA by partial acidic depurination. Amino groups were then introduced into the abasic sites by reaction with ethylenediamine and reduction of the aldimine bonds formed. It was found that DNA coul...
متن کاملPolyacrylamide gel electrophoresis of isoenzymes from Entamoeba species.
In this preliminary report, we describe a polyacrylamide gel electrophoresis technique for the resolution of isoenzyme patterns of four isolates of Entamoeba histolytica and one isolate of Entamoeba coli. Our findings were similar to previous findings for three enzyme systems: maleic enzyme (malate dehydrogenase [EC 1.1.1.40]), hexokinase (EC 2.7.1.1), and phosphoglucomutase (EC 2.7.5.1). We fo...
